Balloon Powered Jet Car with Sweet Rimzzz By: thehans

While visitng from Germany, my nephew wanted me to print something for him to play with using my Lulzbot AO-100 3D printer. Naturally I went straight to Thingiverse and found a cool Balloon Powered Jet Car that I could print up in about two hours with everything on a single plate. The video below is a timelapse of the print which was sped up about 1500%. 

 

I sliced the model at a .40 layer height, 25% infill, and speeds were around 70mm/sec on Peremiters, Small Peremiters, and  Infill. With such a thick print, I decided to squish the first layer a little more than normal. I chose 70% over the usual 90%. This turned out to be an issue with the wheels as it made one side of the wheels a little wider than the other 99%. A quick sanding took care of this though.

I used finishing nails to mount the wheels and used a drill bit to clean up the car axel holes, then a slightly larger drill bit to open up the wheel axel holes a little. Unfortunately the balloons I had on hand were just not powerful enough to push the car across the floor. Still, my nephew had a blast watching the car form infront of his eyes. I honestly think that he sat and watch the entire print.
